Abstract In this paper, graphene was prepared from flake graphite by Hummer method. Silver nanoparticles were loaded on graphene by a method of in situ reduction. The silver-loaded graphene material was mixed with epoxy resin to form silver-loaded graphene/epoxy resin composite with excellent performance. This property should be due to the combinative of these three materials. At the same time, the effects of blending ratios of silver-loaded graphene on the properties of the composite were researched, including tensile strength and elongation at break. The results show that the composite exhibited best enhancement effectiveness of tensile strength when the mass percentage is 0.05%. The best strengthening effect of elongation at break were obtained when the mass percentage is 0.1%. By researching of curing temperature, it was found that the optimized scheme of the curing temperature is 100 ℃ with the addition of 0.05%. Contemporary, the thermal decomposition of the modified composite can be slowed down effectively. That is, the thermal stability of epoxy resin was enhanced.
